It's time to celebrate for alt-rockers Imagine Dragons, as their debut album has just gone platinum (1 million copies sold) in the U.S.

Night Visions was released in September 2012 and has since spent 40 weeks on the Billboard album chart, with a current hold on the No. 7 spot.

The album has blown up the singles charts as well, with It's Time and Radioactive both carving out space in the top 40. The popular tunes gained recognition in spots for teen flick The Perks of Being a Wallflower last fall and the new ad campaign for Beats By Dre Powerbeats headphones starring LeBron James, respectively.

Imagine Dragons is playing the festival circuit and headlining a North American tour, with European dates set for later this year. The band is scheduled to play Good Morning America's summer concert series in New York July 5, before stopping by Late Night With Jimmy Fallon July 26.

In a May 2012 interview with USA TODAY, frontman Dan Reynolds spoke of the rock group's beginnings playing casino gigs, living off "Taco Bell bean burritos and ramen noodles."

"It's a lot of being dirty, not eating, playing for five people and one of them is the bartender," Reynolds said of the musician's life. "But I really believe that you don't do music because you want to, you do it because you have to."
